  • Human pluripotent hematopoietic colony stimulating factor, method of production and use
    Publication number: 20050063946
    Abstract: Highly purified Pluripotent hematopoietic colony-stimulating factor (pluripotent CSF), a glycoprotein (MW 19,600) constitutively produced by human tumor cells has been highly purified from low serum-containing conditioned medium to apparant homogeneity. Pluripotent CSF supports the growth of human mixed colonies (CFU-GEMM), granulocyte-macrophage colonies (CFU-GM), early erythroid colonies (BFU-E) and induces differentiation of human leukemic cells. The specific activity of the purified pluripotent CSF in the CFU-GM assay is 1.5×108 U/mg protein.
    Type: Application
    Filed: October 5, 2004
    Publication date: March 24, 2005

  • Human pluripotent hematopoietic colony stimulating factor, method of use
    Patent number: 6419918
    Abstract: Highly purified Pluripotent hematopoietic colon-stimulating factor (pluripotent CSF), a glycoprotein (MW 19,600) constitutively produced by human tumor cells has been highly purified from low serum-containing conditioned medium to apparent homogeneity. Pluripotent CSF supports the growth of human mixed colonies (CFU-GEMM), granulocyte-macrophage colonies (CFU-GM) early erythroid colonies (BFU-E) and induces differentiation of human leukemic cells. The specific activity of the purified pluripotent CSF in the CFU-GM assay is 1.5×108 U/mg protein.
